Claims.

The present invention relates to packages for articles. More particularly, it relates to new and improved container construction which may carry indicia on the several walls thereof that are adapted to cooperate in a highly entertaining and educational manner.

Broadly, the invention comprises at least two enclosures having walls and hinged together so as to be swingable about an axis. The several walls of the enclosures may carry indicia portions and the indicia portions on one enclosure are adapted to cooperate with associated indicia portions on the other enclosure to form more complete indicia when the enclosures are swung about their common axis to bring the several indicia portions into cooperating relationship. Preferably, the enclosures are containers in which articles of merchandise may be displayed although this is not necessary.

In a representative embodiment, substantially similar enclosures of suitable shape are employed which are secured together so as to be swingable about a common axis to bring adjacent indicia bearing sides thereon into cooperating relationship. The enclosures may be secured to a supporting member which may have indicia bearing flaps adapted to cooperate with the indicia'bearing walls of the enclosures to form more complete indicia. In this fashion, a plurality of more complete indicia may be selectively formed which may tell a story in pictures, for example.

According to another embodiment, window portions may be formed in the enclosures, which are adapted to cooperate to form a single viewing window or proscenium arch construction when the enclosures are swung into viewing position, In this form, cooperating indicia bearing members inside the enclosures may cooperate to form complete indicia when the enclosures are swung to form the viewing window. Other window portions may be formed in the enclosures which cooperate to form a second viewing window through which articles of merchandise or other complete indicia formed by cooperating indicia portions inside the enclosures may be viewed. Inserts may be provided for the enclosures to enable the indicia portions to be changed as desired.

The invention also contemplates the provision of means for retaining the enclosures together to form an integral package as may be required for shipment and distribution. v y

Fig. 19 is a top view in horizontal section of a packaging assembly constructed in accordance with the present invention.

In the representative embodiment illustrated in Figs. 1-5, inclusive, the novel package of the invention comprises, for example, a pair of similar enclosures secured to a retaining memberin such fashion that they can each be swung through 90 about a common axis. As shown inFig. l, the retaining means may comprise for example, a substantially rectangular member made of any suitable suificiently rigid'material such as cardboard, paper, plastic, impregnated fabric, or the like, scored parallel to the narrow edge thereof to form two outer flaps 3| and 32 and two adjacent support'portions33'and 34 to which a pair of enclosures are'adapted to be secured as described in greater'detail hereinafter.

In Fig. 3 is shown 'a blank 35 for one enclosures member which is suitably scored to provide the side portions 36, 38, 4|, and-'43, the flaps 39 and 40 at opposite ends of the side portiori38, the flaps-44 and 45 at oppositeends of theside portion 43, the opposite end closure members 31 and 4-2 onthe side portions36 and 4|, respectively, "and a securingflap46 by means of whichthe side portion 36 may be attached to the side portion 43 to form an enclosure.

Fig. 2 illustrates a blank of another en- I closure member-which is appropriately scored to provide the'side portions, 50, 53 and 56, the flaps 54 and 55 secured at opposite ends of' the side portion 53, the flaps 5| and'52, secured at opposite ends of the side portion 50, the'opposite end closure members 49 and 51, and a securing fla'p 58; by-means of which-the side portion 48 may'be secured to the side portion50.

- To assemble the novel package of the invention the' blank 35 is folded at the scored lines and the flap 46 is secured under the edge of the side portion-43'inany-"suitable manner as by gluingystitching or stapling, for-example, to form an enclosure of substantiallyrectangular'crosssection. The 'opposite'end flaps 39, '40 and 44, 45"are folded inwardly and the opposite end closure members 31 and'42, respectively, arefolded down over'them' toform the finished enclosure. Theblank 41 is folded and assembled in asimilar manner and the two enclosure members 59 and Elly-respectively, '(Fig. 4:)"are secured to the supportportions'33' and-34 of the'retaining means "38 '(Fig. 1), preferably in inverted relationgto "one another. This may be accomplished in any suitable manner as by gluing, stitching,or stapling, for example, the support portions'34 and 33 of the retainingmeans to two side portions as the side portions 36 and 56' of the blanks' 35 and'41, respectively, for example.

'"As shown in Fig. 1, the outer flaps 3| and 32 of the retaining means 30 may carry indicia'portions 6| and 62. Similarly, the side portions, '53 and 48 are the opposite end closure members 49 and 51 of the blank 41 in Fig. 2 may'also carry indicia portions 63-, 64, 65766 and 61, respectively. Also, the side portions 38, 4|, 43 and the'opposite end closure members 31"and'42 of the blank'35 (-Fig. 3') may carry-indicia'portions'68; 69, 10, 1|

and 12, as shown. These indicia portions are preferably so selected that when the package is in the assembled position as shown in Fig. 4, the indicia portions of any two adjacent faces of the retaining means 30, or of the enclosures 59 and 60, will cooperate to form a more complete indicia. Thus, in Fig. 4, the indicia 61 on the end closure member 51 and the indicia portion 1| on the end closure member 31 may cooperate to form the picture of a rabbit, for example. Obviously, no indicia portions are needed for the securing side portions'36 and-56, thus effecting a saving in the cost of manufacture.

It will be noted that by swinging the enclosures 59 and each rearwardly through 90 to bring the support portions 33 and 34 of the retaining means 30 into back to back relation- -.ship,.the-.rear.faces of the outer portions 3| and "32 of the retaining means 30 may be brought into abutting relationship. Accordingly, cooperating .indicia can also be provided on these rear faces which will cooperate to form a more complete indicia when the assembled package is swung into this position.

If desired, the several indicia portions'on' adjacent sides of the completed article may each cooperate to form a complete picture and'the entire set of'pictures may serveto tell a' story which may be any of'the well known children's stories, for example. Alternatively, each indicia portion may comprise only part of a relatively large picture such as a panorama, or cyclorama, for example, In such case,the indicia portions on adjacent sides of the articlemay cooperate to form only a portion of the entire picture. Other uses for the novel package assembly according to the invention will be readily apparent to those skilled in the art.

If desired, the enclosures'59 and 60 may be 'provided with cooperating viewing apertures through which cooperating indicia located within the enclosure membersmay be viewed, as shown in the embodiment illustrated in Figs. 6-15,"inclusive. This form of the invention also includes means for looking a pair of enclosure members 59 and60 in the assembled position as required for shipment or distribution, for example.

Referring now to Fig. 8, the enclosure member blank 35 is substantially like the blank shown in Fig. 3 and like parts are designated bylike primed reference characters. It differs in that two adjoining side portions36 and 38', for example, are provided with adjoining apertures 13and'14, respectively. The blank 41 in Fig. 7. is likethe corresponding blank in Fig. 2 and like parts are designated by like primed reference characters. It "differs in that two adjoining side portions 56 and 50, for example, are provided with adjoining apertures'15 and16, respectively. The retaining means 3|1"'(Fig. 6) is also like the retaining meansl30 iri Fig. l and like primed referenec characters are used to designate like parts. It may also have cooperating aperture portions 11 and 18 formed in the supportportions 33' and 34', as shown. Also, the outer flap 32 may. have secured thereto a front portion 19 terminating in a securing tab '80. The flap 3|, similarly, may have secured thereto a front portion 8| terminating in a tab 82, and a slot 83 which is adapted to receive the locking tab 80. The enclosures 59 and 60' are assembled as before, with two side portions as the side portions 56 and 36, for example, of the blanks 41' and 35, respectively, secured to the support portions33 and'34', respectively, of the retaining means 30 (Figs. 9 and 10). Preferably,pone of the enclosures is mounted in inverted relation to the other, as shown. The apertures and. 13 in the enclosures 59' and 60, respectively, may be so shaped and positioned as substantially to register with the apertures 11 and 18, respectively, in the support portions 33' and 34', respectively.

If desired, the side wall 43' of the blank 35' may be secured in any suitable manner as by a suitable adhesive, for example, to the front face of the outer fiap 32' of the retaining means and the side portion 53 of the blank 41' may be secured in a similar manner tothe front face of the outer flap 3 I of the retaining means 30'.

With the enclosures 59 and 60 thus assembled and secured to the retaining means 30 of Fig. 6, the front portions 19 and 8| of the retaining means 30 are folded over the front faces M and 48, respectively, of the blanks and 41', respectively, with the locking tab 82 between the enclosures 59' and 80'. The locking tab 80 is bent inwardly and passed through the slot 83 to a position between the side walls 50' and 88' of the enclosures 59 and 60, respectively, as shown in greater detail in Figs. 9 and 10.

If desired, the inner faces of the walls of the enclosures 59 and 60 may carry suitable indicia portions adapted to cooperate to form more complete indicia that can be viewed through the apertures 13, 15, 11 and 18 (Fig. 10), or through ,the apertures 14 and 16 when the assembly is in the Fig. 15 position or both. Also, indicia 1 bearing inserts may be disposed within either of the enclosures 59 and 60 to add additional interest, if desired. For example, an insert 84 out out in the shape of a duck as shown in Fig. 11 and provided with a slot 85 may be retained in viewing position in any suitable manner as by the adjacent walls of the enclosures 59 and 60, which define the apertures 14 and 16, as shown in greater detail in Fig. 10.

Obviously, indicia may be provided on inserts adapted to be placed within either of the enclosures 59 or 60 parallel to the walls there-' of, such indicia being designed to cooperate to form more complete indicia when the enclosures 59' and 60 are swung into operative relationship. Also, such inserts may be disposed diagonally within the enclosures 59 and 60, as

shown in greater detail in Figs. 12-15, inclusive.

Thus, diagonal inserts 86 and 81 may be inserted within the enclosures 59 and 60', as shown in Fig. 13. As shown in greater detail in Fig. 12, the diagonal inserts 86 and 81 may carry indicia portions 88 and 89, respectively, which are adapted to be viewed through the adjoining apertures 11 and 18 in the retaining means 30'. When the enclosures 59' and 60 are swung rearwardly through 90 to the position shown in Fig. 15 and the diagonals 88 and 81 are viewed through the cooperating apertures 14 and 10, the indicia 88 and 89 appear reversed as better shown in Fig. 14.

Where the diagonal inserts 86 and 81 are made of relatively non-rigid material such as light paper, for example, additional support may be afforded by other diagonal supports 86a and 81a located at right angles to the inserts 88 and 81 (Fig. 13). The diagonal supports 85a and 91a may be provided with vertical slots I29 and I30,'respectively, (Fig. 12) within which the diagonal inserts 88 and 81 are adapted to be received. Preferably, the supports should not extend up to the lower edges of the apertures 6 11 and 18 so as not to obscure the indicia to be viewed. The supports 88a and 81a may also p vide support for inserts like the duck 84 shown in Figs. 10 and 11.

As shown in Figures 12a and 14a, diagonal inserts 86 and 81' may, if desired, carry indicia 88' and 89 representing a foreground to be viewed against a background which may include indicia 88a and 88b (Fig. 12a) and 89a and 89b (Fig. 14a) carried by the sides the enclosures 59' and 60. In such case, the inserts 86a and 81a should be smaller than the sides of the enclosures 59' and 60' so that the indicia 88a, 88b and 89a, 89b carried by the walls of the latter will be visible. By providing different indicia i. e. indicia 88a and 88b and indicia 89a and 89b on the inside walls of the enclosures 59' and 60, it will be apparent that the foregrounds represented by the diagonal inserts 86a and 81a can be viewed against two different backgrounds corresponding to the Fig. 13 and Fig. 15 positions of the device, respectively.

Instead of securing enclosures 59 and 60 to a separate retaining means 30', the entire package assembly may be formed from a single blank, as shown in Figs. 16-18, inclusive. In this embodiment, a blank 90 is used which may be substantially rectangular in shape and may be scored substantially parallel to the narrow ed e thereof, for example to form left and right rear enclosure walls 9| and 92, respectively, left and right side walls 93 and 94, respectively, front walls 95 and 96, left and right inside walls 91 and 98, respectively, and a securing tab 99 adapted to be attached in any suitable manner as by adhesive, stitching or look tabs, for example, beneath the front wall 96.

The left front wall 95 may, .as desirable, be provided with top and bottom flaps I00 andIOI and the right front wall 96 may be similarly provided with top and bottom flaps I02 and I03.

The left and right rear walls 9| and 92, respectively, may, as desirable, be provided with upper closure members I04 and I05 and a central locking tab I06 which also cooperates to form part of a closure for the two enclosure members. Bottom closure members I01 and. I08 may also be provided for the left and right rear Walls 9I' and 92. To assemble, the securing tab 99 is attached over or. under the front Wall 96 in any. suitable manner as by gluing, stitching or stapling, for example, and the blank is folded along the score lines as shown. With the left and right inside walls 91 and 98 lying directly over the rear walls 9| and 92, staples, stitching or other suitable securing means I09 and I I0 are inserted at the upper and lower portions of the score line II I as indicated in Fig. 18, thus forming hinges. The upper flaps I00 and I02 are folded inwardly and tabs I I2 and H3, respectively, are bent downwardly within the enclosures. The lower closure members I01 and I08 are folded inwardlyand the tabs H4 and H5, respectively, are bent upwardly into the enclosures. The lower flaps NH and I03 are then bent inwardly and the tabs I I6 and I I1, respectively, thereon are inserted within the slots I I8 and H9 formed. in the lower closure members I01 and I08, respectively. The top closure members I04 and I05 are bent downwardly and the tabs I20 and I2I thereon are inserted within the slots I2 I' and I22, respectively formed in the upper flaps I00 and I02, respectively. 1

The locking member I06 is provided with two adjacent :tabs Ina-and C-IMrahaVing a slot :125

It will be further :understood that theseveral "embodiments described in. detail are susceptible of considerablemodification withinthe scope of the invention. whilethe. foregoing description indicates that cooperating.- indicia .portions may a be formed on adjacentwalls of the article',.obviouslythe adjacent indicia need have no relation to? one another but may bezentirely different, if

desired. Also, the indicia may be entirely elimi- "nated if the article is to* servesolely as a container. Inrcertain applications, as where' the -;'device serves only as a top or as a greetingcard device, for example, the opposite::end closure members maybe eliminated, as desired, 50 that theenclosures may have side Walls'only.

In packaging loose goods such as cereals, soap powder and thelike. in the novel package assem- "ample.

bly orthe invention; .obviously, it is not feasible to provide the viewingapertures in the enclosures 59 and while the latterare serving as containers.

In such case, the apertures may be defined on the enclosures in any suitable'manner as'by printing or incomplete perforation, for ex- After the contents have been removed,

= the outlined portions may be cut or pushed out to form the viewing apertures.

The material thus "removed may be appropriately scored and -may carry suitable-indicia so as to enable one or more inserts to be cutmout therefrom .for insertionwithin the enclosures. Alternatively, the enclosures maybe made of'plastic which is transparent in theadjoining portions where the viewing window is to be located, and is substantially opaque elsewhere.

Obviously, the viewing apertures inthe several embodiments illustrated may be covered by any suitable transparent material suchas 1 cellophane, for example, which maybe secured either to the inside or to the outside-walls of the article,

.18 as desired,'or the assembled'package may-beprovided with a cellophane binderor wrapper. Also,

in the-embodiment illustrated in Fig. 13,-for example, additional viewing apertures may-be provided in the enclosure so that therear faces of f the diagonal members 86 and 81 may be viewed or so that articles may be disposed on either. or

both sides of either or both diagonal members 86 and 81 where they will be readily available as illustrated by Fig. 19.

for inspection.

Where a retaining means is used, as in Figs. 1 and 6, for example, the portions 33 and may be provided with flaps-at the upper and lower endsthereof by means of-which' they maybe secured to the enclosures 59 and 60. -Thus, the portions 33 and 34 might be providedwith separate upwardly extending flaps appropriately .scored and adapted to be folded downwardly over the endclosure members 51 and 31,-respectively, and terminating in tabs adapted to be inserted between corresponding tabs on the closure :members 51 and 31 and the upper inside-faces of theside walls and 4|, respectively. Similar downwardly extending flaps mightbe provided on the portions 33 and 34, properly scored and adapted vto -.be folded upwardly over the lower inside faces of the side walls 56 and 36, resepectively, and between the=latter and the tabs formed on the end closure members 42 and",

respectively. The locking-tab constructionJIlB of the Fig. 16- embodiment might also be employed in this modificationto hold the twoenclosures in assembled relationship.

While onlytwo enclosures have been shown in the several embodiments described above, obviously, the novel package assembly of the invention can be made with more than twoenclosures For example, four similar enclosures I30, I3I, I32 and I33 might be assembled in a string with, adjacent pairs being mounted for swinging movement about a common axis to afford aser-iesof-substantially parallel axes I34, I35 and I 36, these axes lying alternately atfrontand-rearcommonedges of the adjacent enclosures when the latter are disposed in abutting relationship in a-single line to form an assembly of substantially rectangular shape.

The several-embodiments described above'are intended to be merely illustrative ofthe-invention; It willbe readily apparent to those skilled in-the. art that the novel packageassembly of the invention can be constructed in other -forms than the-several specific embodimentsshown.
